ELLSWORTH TILDEN, F DULU'TH, MINNESOTA uOUNIJING SIGNAL DEVICE FOR AUTOMOBILES.

Specication of Letters Patent.

Patented Aug. 5, 1919.

Application filed February 19, 1919. Serial No. 277,938.

Tooll whom it muy rom/ern, Be it known that I, Ennswon'rn TILnEN, a citizen of the United States. residing at Du- Ulutll, in the county of St. Louis and State of Minnesota, have invented certain new and useful Improvements in Sounding Signal ADevices for Automobiles; and l do hereby declare the following to bc a full, clear, and

. be given an alarm in the event of the automobile to which it is applied being used While the device is set.

`The invention comprises a simple and efficient device of this character havingr various details of construction, combination and arrangement of parts which will be hereinfatter fully described, shown in the accompanying,r t rawings and then specifically delined in the appended claims.

,I illustrate my invention in the accompanying drawings which, with the letters of reference marked thereon, form a part of this application. and in which:

Figure 1 is a side elevation of the device. Fig.v 2 is a central sectional view, and Fig. 3 is a transverse sectional view. y, Reference now being had to the details of the drawings by letter:

A and B designate two sections of the easing, which are preferably ot' cylindrical outline, and are held spaced apart by means'of the straps C. Mounted within the casing A is a cylindrical outlined block D with its upper surface E dished, and having a cen tral opening F in the bottom thereof. H designates an alarm bel] fastened with-in the section A immediately above and adjacent to the upper dished surface of the block D. Mounted upon the central axis bet-Ween the space intermediate the two sections are two disks I and K, having peripheral numbers L and perforations N, identiiied by each numeral and formed in the disks adjacent to the marginal edge thereof. When said disks are adjusted in place their outer peripheries will be ush with the outer faces of the sections of the casing.

Mounted Within the lower section A of the casing is a tube .0 which is slotted down from its upper end upon its inner portion, and Q, designates a rod mounted to have a longitudinal movement within said tube, and is provided with a lateral extending handle P passing through a slot in the easing sec tion A, and forming 11n-ans whereby the rod Q may be raised and lowered. A second rod Q is also mounted Within the tube O and is given an upper longitudinal movement through thc. medium ol the rod when the latter is raised. The rod Q has a vlaterally extending L shaped arm Q? extending through the slot in the tube 0 and having at its outer free -upturned end a concaved recess Q3 adapted to receive a ball R. The under surface of the block D has a radial channel' D formed therein, in which said L- shaped arm is adapted to move the ball, being held at all times centrally in ulinement with the hole F in the block D. A Washer Q* is mounted about the rod Q and is adapted to bear with sufficient friction against the wall of the tube in which it is mounted to hold the same in different adjusted positions.

`Mountei'l within the section B is a tubular casing T having a rod T mounted therein, and S is a knob fastened. to the rod und passed through a slot in the casing section B. Said rod T has an integral lug T'" adapted to conform to and 'pass through ap-` ertures N and N2 when the same come in registration with each other and underneath the pin T. It will be noted that the rod T' and the perpendicularly disposed portion of the rod Q are in alincment with each other, and when the perforations N and N in the two disks, representing certain combinations, are brought into registration with each other, the rod T may be pushed down through the registering apertures and against the top of the rod Q for the purpose of returning the same to its lowest and normal position, the ball moving down also hy gravity and resting in the recess in the end thereof.

In, operation, attached to any bile,

device is adapted vto be suitable part of an automosuch as the running-board and when the `driver leaves the automobile in the street or. other plae, the signal device is set by raising the button P attached to the rod Q raising the rod and with it the tube within the L-shaped extension forcing the ball to the surface of the block D whereit will roll back and forth against the bell and sound the alarm. The arm holdin the ball in position to sound the alarm will be held in its raised position until returned by pushing down upon the rod T having a handle or knob S projecting therefrom, but before it is possib e to move the rod T so that it will push the rod Q, toits normal position, it will be necessary to know the combination of disks, sothat the disks may be rotated to bring certain numerals designating the apertures N and: N together, one above the other, which will indicate that said a er1 tures are in position to ermit the lug to pass through the two dis s. It will be noted that the lug T2 is located a Sl ht distance from the lower end of the pin and which will permit said lower end to always engage one or another of the several apertures in the upper disk, which will lock the same from rotating, the lower disk, however, be ing free to rotate until the two articular apertures N and N are brought into registration with each other and in alinement with the pin T.

By the provision of a si al device embodying the features of my invention, it will be noted that means is provided whereby any tampering with an automobile will be readily 'detected by the signal which will be sounded by the ball rolling against the bell.

What I claim to be new is':

1.' A sounding signal of thetype described, comprising a casing made utpsof two sections spaced apart, rotatable dis with perforations therein mounted within the spaces between t disks and having peripheral numerals identifyin the perforations in the disks, a block wit in the lower section having its upper surface dished and provided with a ntral aperture, a bell positioned over said dished portion of the block, a ball and support therefor, and means having a part extending outside the casing for raisinv said support and which will raise the ba throu h the aperture .in the block and permitV t e ball to roll against the bell, and

ing a part extending outside the casing for raisin said support and which, will raise the bal through the aperture in the block land permit the ball to roll against the bell,

a movable rod mounted in the upper section and having a knob extending outside the casing adapted, when certain apertures of the disks are in regu'stration, to be permitted to pass through the same to return said support and ball carried thereby to their normal positions.

3. A sounding signal of the type described, comprising a casing made up of two sections spaced apart, rotatable disks with perforations therein mounted within the spaces between thedisks, and havin peripheral numerals identifying the per orations -in the disks, a block with the lower section having its upper surface dished and provided with a central aperture, a bell positioned over saidv dishedyporton of the block, a vertically movable rod having a 'lateral extension, and ball carried thereby, means for raising said rod to permit `the ball to enter the dislicd portion of the block, a rod in the upper 'portion of the casing in aline ment with the rod in said lateral extension, and designed to be passed throu h' said combination of apertures in the dis is to return the rod carrying said ball to its normal position. y

In testimony whereof I hereunto aiiix my signature in presence of two witnesses.
